Momentum = mass x acceleration
5 x 2 = 10 kg. m/s
You need distance and time to find average speed.
Answer:
hope this helps
Explanation:
an object that's less dense than water floats (eg , ball) because the water it displaces weighs more than the object does. If you've ever tried pushing a beach ball underwater , you've felt this principle in action. As we push the ball down , it pushes back up .
Answer:
Explanation:
The question relates to motion on a circular path .
Let the radius of the circular path be R .
The centripetal force for circular motion is provided by frictional force
frictional force is equal to μmg , where μ is coefficient of friction and mg is weight
Equating cenrtipetal force and frictionl force in the case of car A
mv² / R = μmg
R = v² /μg
= 26.8 x 26.8 / .335 x 9.8
= 218.77 m
In case of moton of car B
mv² / R = μmg
v² = μRg
= .683 x 218.77x 9.8
= 1464.35
v = 38.26 m /s .
